Abox of powdered laundry detergent contains 5.2 ounces of detergent. it takes 0.7 ounce of detergent to clean a load of laundry. how many full loads can by cleaned with 3 boxes of this detergent?

So a box has 5.2 oz
it takes 0.7 oz to clean one load

with 3 boxes (3 times 5.2) how many can be cleaned

3 times 5.2=15.6
15.6/0.7=156/7 how many loads=22 and 2/7 =22.285 loads or less than 22 loads (since you can't clean a decimal of a load)

22 Loads is the answer

Wait what the question
